I use CAPSLOCK as my fn key, it's right under my pinky, no need to move my hand. On my second layer I have arrow keys set on hjkl so in programs that don't support vim key bindings I can use them without moving my hand from the home row. This is a more efficient way to use the arrow keys compared to a standard keyboard where you have to move your hand out of the home row.
